EU / KOREA - Regions both known for explosive executes and strategic plays. Superior Aim and High IQ plays. Korea is a one team region btw
NA - Adapted APAC's Agression and had a lot of strategic plays. Mid aim ( Diamond - Ascendant EU aim )
BR - Good aim but hardly adapts to the agression meta
APAC - One team region Paper Rex, good aim and agressive plays. Rest of apac probably lacks aim or strats or both.
JP - Underdog's advantage gives edge to the region. Relies a lot on hero plays of two players. Zeta proved the international community wrong and bring in the Japanese pride.
LATAM - I don't know about their play style but they have underdogs advantage same as Japan but doesn't have the recognition from international community.
